[UPDATE: The all new 2015 Porsche 911 Carrera GTS models became official, you can read all about them here!] -The 2015 Porsche 911 GTS will make its debut in November, at the 2014 Los Angeles Auto Show but it appears that things are getting more interesting ahead of the German sports car’s debut. According to Motor Trend’s Jonny Liberman, the new Porsche 911 GTS is codenamed 992 and not 991.2 as many of you folks would think.

Lieberman says that there are some big changes ahead but no more details were released. The 911 (992) GTS is expected to use the same 3.8-liter boxer engine that powers the current 911 Carrera S capable to deliver over 400 hp.

The previous 911 Carrera GTS was powered by the same 3.8-liter engine that produced 408 hp and 420 Nm of torque available at 4,200 rpm.

However, the current Porsche 911 (991) GTS packs 400 hp and can accelerate from 0 to 100 km/h (62 mph) in 4.1 seconds in Sport Plus mode and when equipped with PDK. Top speed is 187 mph or 302 km/h.

We expect the upcoming 911 (991) Carrera GTS to be faster but we are eager to find out which are the big changes.
